SK Telecom announced on July 18 that its two technologies regarding the control and interworking of quantum cryptography communication networks have been adopted as new work items at the ITU-T meeting held in Geneva, Switzerland. They will be approved as international standards through discussions among ITU-T member countries.

The two technologies chosen as work items are: “Quantum Key Distribution (QKD) Network Interworking – Software Defined Network Control”; and “Quantum Key Distribution Network Federation Framework.” These two technologies are essential for the popularization of quantum cryptography communication technologies.

The “Software-Defined Network Control System for Interworking Quantum Key Distribution Networks” enables telecommunications companies to manage their existing communication networks and QKD networks in an integrated and efficient manner.

It also enables integrated management of quantum crypto communication networks using QKD from different equipment companies, which will greatly boost the growth of the related ecosystem, as telecommunications companies will be able to work with multiple QKD equipment companies to deploy quantum-powered networks.

The ‘Quantum Key Distribution Network Federation’ can be likened to international roaming between mobile operators. Just as international roaming provides users with mobile services across national borders, the ‘Quantum Key Distribution Network Federation’ enables the provision of quantum-safe communication services for customers regardless of the QKD network they are on. are located, supporting interworking/federation between QKD networks of different service providers.

In the future, this technology should not only enable the federation of the QKD-equipped national backbone network and the QKD networks of telecommunications companies to support common roaming services in the event of an emergency, but also allow the federation of satellite communication networks and QKD networks to offer a new range of quantum cryptography communication services in the era of 6G mobile communication.

At the same time, in collaboration with the SK Broadband Consortium and ID Quantique, SK Telecom implemented projects for the Ministry of Science and ICT, building a pilot QKD infrastructure and developing application services for 17 different institutions in the sectors public, medical and industrial. Additionally, the company is currently working to expand into the defense and public markets in cooperation with competitive Korean crypto companies.

“ITU-T’s approval of these two items has significant significance as they will play a pivotal role in accelerating the adoption of quantum cryptography communication worldwide,” Ha Min-yong said. , director of development of SKT. “We will continue to drive the growth of the quantum ecosystem by actively participating in the international standardization of quantum technologies and developing compelling services and business cases.
